Reed Beds

Keytec 642

Reed beds are used by the water industry for the treatment of ‘brown' water in the small rural communities. This approach to water treatment is environmentally friendly and requires 5m² of bed per head population. Industry also favours the use of reed beds in the treatment of their production process water. For example in the brewing and mining industries.

Liner

Our approved product Keytec 642 can be supplied and installed by Keytec technicians.
Keytec 642 is a low density polyethylene (LDPE), with a polyester reinforced scrim having a proven performance record, exhibiting high tensile strength and UV stabilisation to withstand the effects of the environment.
We are able to fabricate this product into panels, thus minimising site welding, which allows for rapid and secure installation in poor weather conditions.

Application

The excavated reed bed base is lined with sand or geotextile and the fully welded prefabricated liner is installed to the formation. Where pipe penetrations occur, top hat sections are welded and sealed to the main membrane. The bed is then overlaid with geotextile to protect the liner from puncture as the bed is filled with gravel. Having already installed pipe inlets and outlets the gabions are filled with stone at opposite ends. The bed is then planted with Phragmites Australis reeds which passes the oxygen down the root system (the rhizosphere). Polluted water around the roots is then purified by the dense population of micro-organisms living in the rhizospere which destroys harmful bacteria before the water is discharged into streams or rivers.
